Kingsdown is a hamlet in the civil parish of Box, Wiltshire, England. It is about 1.5 mi south-west of Box village and 1.2 mi east of Bathford, across the county border in Somerset. At the top of Doctor's Hill, Kingsdown House is a three-storey ashlar house from the early 18th century; its formal front with parapet and corner urns was embellished in the 19th century with a Corinthian porch and a roof-height clock. There was a private asylum here from the 17th century to the mid-20th, latterly called Kingsdown Nursing Home. The house and its adjacent 19th-century buildings are now in residential use. A Methodist chapel was built in 1869 and rebuilt in 1926. By 2003 it was a private house. There is a pub, the Swan Inn. Kingsdown Golf Course is on higher ground to the east of the hamlet.
